Hi

Have you passed the technical interview yet? If not, you should be able to answer the following questions with no effort.

"Write a function sum2(n) that returns the sum of the of the binary digits in n. For example, sum2(7) should return 7."

If you, just most of /prog, requires more than 5 minutes to solve it, then I'd recommend that you take up something a tad bit easier. Like say, working a cash register at your local Target.

Correction. sum2(7) should return 3. This is because 7 in binary is 111. And the sum of 111 is 3.
